BRCA-related breast cancer appears at an earlier age than sporadic breast cancer. [9]: 89–111 It has been asserted that BRCA-related breast cancer is more aggressive than normal breast cancer, however most studies in specific populations suggest little or no difference in survival rates despite seemingly worse prognostic factors.

The chromosomal location of BRCA1 was discovered by Mary-Claire King's team at UC Berkeley in 1990. [21] After an international race to refine the precise location of BRCA1, [22] the gene was cloned in 1994 by scientists at University of Utah, National Institute of Environmental Health Sciences (NIEHS) and Myriad Genetics.
The BRCA1 and BRCA2 genes are centrally involved in HR, DNAdamage repair, end resection, and checkpoint signaling. Mutational signatures of HRD have been identified in over 20% of breast cancers, as well as pancreatic, ovarian, and gastric cancers. BRCA1/2 mutations confer sensitivity to platinum-based chemotherapies.
9% of breast cancer cases were BRCA1/BRCA2 mutation carriers; 12% of breast cancer cases who started OCs before age 20 were BRCA1/BRCA2 mutation carriers vs. 4% of breast cancer cases who started OCs after age 20; but; there was no significant difference between breast cancer cases with or without BRCA1/BRCA2 mutations in: total duration of OC use
